Abstract
An image processing apparatus comprises an error diffusion processing section,for performing error diffusion processing with quantization levels of three or above on image data x(i, j) for producing an output; and a second error diffusion processing section,for performing error diffusion processing with quantization levels of three or above on the data outputted from the first error diffusion section,for outputting image data y(i, j). Quantization levels of three or above of the quantizer,in the error diffusion processing section,are determined to be desired value. Quantization levels of three or above of the quantizer,in the error diffusion processing section,are determined to be levels each between each neighboring two of the quantization levels of the quantizer,, the minimum level of the image input data x(i, j) and the maximum level of the image input data x(i, j).
